Zina mwa zinthu zomwe zimakhudza mapangidwe a makwinya pakhungu

Kumasulira kwenikweni kwa chibadwa cha minofu yapakhungu ndi momwe khungu lathu limakhalira. Zimatsagana ndi anthu pobadwa. Amapangidwa ndi undulating khungu grooves ndi crests khungu, amene makamaka anakonza mapoligoni ndi pafupifupi zosasinthika. Kuyang'ana mwachindunji pakhungu lopanda kanthu, mukhoza kuona zovuta, zowonongeka, komanso tsitsi labwino lamtundu wolemera kapena wopepuka. Komabe, m’kupita kwa nthaŵi, anthu amapitirizabe kukalamba, ndipo khungu limakalambanso mwachibadwa. Panthawi imodzimodziyo, khungu lomwe nthawi zambiri limawonekera lidzavutikanso ndi zokopa zakunja monga kuipitsidwa kwa chilengedwe, ndikupitiriza kuvulala, ndipo kuchuluka kwa kuwonongeka kwa maselo a stratum corneum kudzasintha. Kuchuluka kwa zikopa zapakhungu ndi zitunda zapakhungu zikusintha, ndipo mawonekedwe okhazikika amawonekanso olumikizana, chiwerengerocho chimachepa, ndipo malo akupitilizabe kukula, kotero khungu limakhala lokwinya komanso lovuta.
Nthawi zambiri, asanakwanitse zaka 25, khungu limakhala losalala, lowala komanso lotanuka. Pambuyo pake, khungu limayamba kukalamba pang'onopang'ono ndipo zizindikiro za thupi zimasintha.
1. Khungu chinyezi ndi zotchinga khungu
Kafukufuku wambiri pakhungu loyipa amayang'ana kwambiri ntchito za stratum corneum, monga momwe amagwirira ntchito posunga madzi komanso ntchito yotchinga khungu. Monga kuphunzira chinyezi, zinthu zachilengedwe zonyowa, ndi kusintha kwa lipid pakati pa maselo a stratum corneum. Kutaya kwachinyontho kumakhala koopsa, kumapangitsa kuti khungu likhale lopweteka komanso lopweteka. Kutayika kwa maselo a epidermal kumasokonekera, zomwe zimapangitsa kupanga dandruff ndi mamba. Chinyezi cha pakhungu chimagwirizana kwambiri ndi chinyezi, kuwala ndi kukongola kwa khungu. stratum corneum yosalala, yochuluka yamadzi imayang'ana pafupipafupi kuti ipangitse kuwala kowala, pomwe cornea youma, mascaly stratum corneum imayang'ana mwanjira yosakhala yachilendo yomwe imapangitsa khungu kukhala lotuwa. Ndi chinyezi chochepa pakhungu, khungu limakhala louma komanso lovuta, ndipo khungu limakhala losalala.
Khungu lokhala ndi ntchito yochepetsera zotchinga lili ngati ambulera yosweka. Sikuti madzi amkati amatuluka mosavuta, koma zokopa zakunja ndizosavuta kuwukira, ndipo kutupa kumakhalanso kosavuta kuchitika. Monga mavuto a khungu okhudzana ndi kutupa: kuyabwa, kuyabwa, kuyabwa, kuyabwa, kufiira, ndi zina zotero.
The photoaging epidermis anasonyeza kukonzanso makulidwe pamene kuwonongeka kunali kochepa, ndi atrophy pamene kuwonongeka kunali kwakukulu. Ma cell a basal layer adasinthidwa ndi atypia yodziwika bwino, ndipo panali ma cell ambiri a dyskeratotic.
2. Dermis imataya mphamvu yake
Khungu laukali limagwirizana kwambiri ndi elasticity ya khungu. Khungu la elasticity limachepa, kufooka kwa khungu kapena makwinya kumawonekera, ndipo kuuma kwa khungu kumawonjezeka. Ma fibroblasts ndi gawo lofunika kwambiri la ma cell mu dermis ya khungu ndipo limagwira gawo lofunikira pakuphatikizika kwa ulusi wachinsinsi komanso matrix a extracellular. Zimagwira ntchito yofunika kwambiri pakukonza mabala a minofu. Ndi zaka, makulidwe a khungu amachepetsa pamene zotanuka ulusi wa pakhungu pang'onopang'ono amachepetsa. Kukalamba kwapakhungu ndikodziwika, komwe kumatha kuzindikirika ngati khungu louma komanso louma, makwinya amachulukira, makwinya, khungu lotayirira, komanso kuchepa kwamphamvu. Zaka zimatsagana ndi kuchepa kwa mapuloteni akutali a khungu, kusowa kwamphamvu kwa khungu, komanso kuwonjezeka kwa kuya kwa khungu komwe kumatsogolera ku maonekedwe a makwinya.
Choncho mavuto a khungu asanapangidwe, tidakali ndi zinthu zambiri zoti tichite. Mwachitsanzo, akhungu analyzerzingatithandize kuchepetsa kapena kuthetsa mavuto a khungu mpaka pamlingo wakutiwakuti mavuto akhungu asanafike!
